pb

Consistently works on macOS, Linux, and Windows, as stated in the README, ensuring broad compatibility for CLI tools.

Allows custom bar characters and styles via methods like pb.format(), demonstrated in the simple example with custom symbols.

Supports multiple progress bars simultaneously through the MultiBar API, shown in the example with separate threads for concurrent tasks.

Broadcast writing integrates with file operations to show progress during copies, as seen in the file copying example using std::io.
